Initializer
init(rawValue:)
Creates a new option set from the given raw value.
Parameters
パラメータ
rawValue
The raw value of the option set to create. Each bit of rawValue
potentially represents an element of the option set, though raw values may include bits that are not defined as distinct values of the OptionSet
type.
Discussion
議論
This initializer always succeeds, even if the value passed as rawValue
exceeds the static properties declared as part of the option set. This example creates an instance of ShippingOptions
with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members.
let extraOptions = ShippingOptions(rawValue: 255)
print(extraOptions.isStrictSuperset(of: .all))
